Round: Resume Shortlist
Experience: There were 3 Job profiles open of opera solutions (Solution Analyst, Analytics Specialist, and Software Engineer). Students are asked to sign just for one profile. There was a test for analytics and software profile and direct interview for solution profile (Consultant profile).
Tips: Spend enough time before choosing the profiles. Spoke to senior who had a similar job and figure out your best suitable profile and prepare accordingly.

Round: Test
Experience: Opera solution conducts workshop for shortlisted candidates. In the workshop, they mostly tell about technical part behind big data management such as Mainframe and Hadoop. After the workshop, the test was conducted. The test had two sections, the first section contains objective questions around 20-25 (I did not remember the exact number). Objective questions were of aptitude type (moderate level of difficulty). The second section contains 5-6 subjective questions, mainly focus on probability again the moderate level of difficulty. 30 students were shortlisted for next round (interview round).
Tips: Start preparing as early you can. Practice problem daily does not wait for last few day. The main point of practice is to develop a habit of increasing accuracy and speed which is the crucial points of aptitude test.
For probability practice, there are online website and blogs you can take help from them. I have listed down some which are used. You should have some prior practice before setting for test otherwise, it would be difficult to do well in the test as some questions are tricky and difficult to solve in the first time.
For aptitude practice, you can refer TIME material, I think that is sufficient.

You get some aspect on which domain you need to work.
